SPECIFICATION forming part of Letters Patent N 0. 643,399, dated February 13, 1900.

' Application filed June 14, 1899. Serial No. 720,464. cu model.)

To all whom it may concern: 7

Be it known that I, SAMUEL S. COLT, a citi zen of the United States, residing at Orange, in the county of Essex and State of New J ersey, have invented certain new and useful Im provements in Door-Frames and Adjustable Jambs Therefor; and I do hereby declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of frames of doors, windows, &c., having adjustable jambs to enable the shrinkage of the door to be taken up with facility and ease, whereby there will be no open cracks or openings between the door and its frame permitting a passage of air therethrough and causing the unsightly appearance due thereto; to enable the door latch or lock-bolt to engage the doorstrike with greater nicety, and thus maintain the door in its locked position; to enable the adjust-able parts to be applied with greater facility and ease to secure a more simple, ef-

fective, and inexpensive construction; to enable the parts to be applied to the j amb without disfiguring the same; to enable that edge of the jamb which coincides-with the edge of the door to be adjustable without materially changing the relation of the opposite edge of said jamb to the casing meeting the same, and to secure other advantages and results, some of which may be referred to hereinafterin connection with the description of the working parts.

The invention consists in the improved doorframe, in the adjustable jamb therefor, and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a horizontal section of the doorframe and door of the improved construction, showing the relation of the operating parts. Fig. 2 is a section of the same, taken at line as, Fig. 1, the door 01 being omitted; and Figs.

3 and at are sectional details showing modifications of construction.

In said drawings, a a indicate the studs of a partition, which may be of wood, metal, terra-cotta, or any other material commonly employed in the construction of partitions between rooms of a building.

I) I) represent, respectively, the lathand plaster attached to the studdin g, the said lath and plaster being cut awayback from the face of the stud toward the doorway to form a chamher .0. I

6 indicates a door-jamb. This is held a little away from the face of the stud a, so that an extension q of the chamber 0 is formed between. door-jamb the same is fastened by nails f f between molded door casings or trimmingboards 9 g, the said jamb and easing being firmly held together by such nails f at the edge awayfrom the door and at the opposite edge adjacent to the point of engagement with the door, and at the side opposite that at which the jamb is commonly rabbeted I have out said j amb away, as at h, at points at which the nails f are inserted, so that the said nails pass through open apertures after passing through the case 9 and before entering the jamb. The nails f being more or less resilient or flexible thus permit a limited amount At the opposite edges of the said I of adjustment of the jamb to or from the door without danger of splitting the wood of either the jamb or casing. A

It is understood that the rabbet to receive the edge of the door may be formed either by planing the jamb or by applying thereto a molding 2' or by both such operations.

The adjusting means comprise, in the preferred construction, a threaded nut 70, having its forward end being provided with a slotted head m, adapted to receive a screw-driver and enable the same to turn said screw in said nut for the purpose of forcing the jamb inward toward the stud a or outward toward the edge of the door.

011 the inner side of the jamb e the screw Z is provided with a washer n, adapted to engage the inner face of said jamb, and with a nut 0 and lock-nut p, by means of which the jamb is caused to move outward with the screw. Said screw Z, it will be noted, is continuously threaded from a point within the jamb e orclosely adjacent to the head at to the inner extremity of the screw. This construction enables the device to be used in con nection with jambs of varying thickness without special fitting to each particularjamb, all that has to be done being to screw the locknut and related parts along the screw until the jamb is reached. Thus constructed I am enabled to quickly and with the greatest ease adjust the jamb in its relation'to the door, and because of the'facility by means of which the screw l and its nut may be applied to the stud and the screw operated in the chamber 0 without interfering with the trimming in connection with the door and its frame I provide a device that is both practical and effective.

In operating the device I apply the adj usting-screw Z and its nuts 7s 0p to the jamb and arrange the said jamb approximately in place in relation to the stud. I then drive the pointed extensions of-the nut Ycinto the stud until the threaded perforation therein is brought into proper position to receive the screw. The adjustments are then made to bring the face of the jamb a into nicely-fitting relation to the door. This being accomplished, the edges of the jamb are fastened in place by means of the casings g g, the casing g being firmly fastened to one edge of the jamb and serving as a fulcrumal center, upon which the jamb is adjusted in, further adjusting operations. By turning the screw by means of an ordinary screw-driver and slotted head at the adjustable edge of the jamb 6 may at any time be brought into proper relation to the door, as before indicated, and the nails passing through the opening or orifice 7t permit of the limited adjustment without danger of splitting the Wood of either the door or casing.

I may under some circumstances modify the construction thus specifically described. For example, instead of nailing directly through from the casing 9 into the jamb e I may nail through said casing a into the studding, such construction being represented in Fig. 1, (1

being the nail thus driven. Furthermore, as indicated by Fig. 4, I may reverse the construction by making the screw Z hollow to receive the male screw-thread 'r, the nut 70 in this case being L-shaped, the pointed projection lying approximately at right angles to the threaded shank. As a further modification the nut 7t may be applied to the easing g, the extension 70 of the said nut being in that event screwed to said casing g.

I prefer, as before indicated, the construction shown in Fig. 1, in which case it will appear that the male thread of the screw Z is continuous from its extremity to a point of passage through the jamb, so that the three nuts 7:; 0 19 may be screwed upon the one thread.

Having thus described the invention, what I claim as new is 1. In combination with the jamb and stud, the screw held to said jamb by the head on, and nut and lock-nut, a nut 7t, arranged on said screw and havingan extension driven into said stud, substantially as set forth.

2. In combination with the jamb and stud,

the screwheld to said jamb and a nut 76, hav- 1 ing the extension 70, substantially as set forth.

3. The combination with the stud and casings g, g, of a ja'mb nailed to one of said casings and adjustable with relation to the other of said casings, and adjusting means, substantially as set forth.

4. The combination with the stud and casings g, g, of a jamb nailed to one of said casings and adjustable with relation to the other,

said jamb being apertured, as at h, and nailed to the other casing at'the aperture, and adjusting means, all arranged and operating, substantially as set forth.

5. In adoor-frame, the combination with the adjustable jamb, of a screw passing through said jamb and having an outer head and a threaded shank, an inner clamping nut holding said jamb against said head, and a threaded socket or nut having a pointed extension driven into the frame and in which the adjusting-screw works longitudinally, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of June, 1899. v
